Any chance you can drop a version of the sleeve that’s adjustable? I need about another half mm or so to get it to actually clamp up when fully tightened.
I bought this router: https://www.amazon.co.uk/dp/B071W37BKD?psc=1&ref=ppx_yo2ov_dt_b_product_details
If you’re in the UK get a length of standard down pipe and slit it, couple of bits of insulation tape around the body, add the sleeve and tape top and bottom and then it is snug.
Here are the step files.

Thanks, I’ve got it sorted now. I printed two new bits, including a pcb mount that I drew up myself. Assembly is nearly complete, but… It appears my entire system is 90 degrees out?
I only realised after spending a few minutes trying to get the router half onto the sled half! (it was about 7:30am. I’m posting this then going to bed!)
What really matters with regards to the orientation of the board, motors, etc? Will it work if I just turn things 90 degrees? Probably not. So do I need to reprint this part with pcb mounting holes turned 90 degrees to compensate?
These should be aligned, but are very definitely out by 90 degrees. (This is still with the orange VonHaus router)
GENIUS! 
OK, so my existing Bosch is definitely not suitable - It is a Bosch GKF 550 professional.
The ‘clampable’ body of it is 85mm long, so it is plainly too short for use in the M4.
I would totally recommend this router, but as a router, not for your M4

@bar Would you be able to advice on these 2 questions? I’m trying to CNC 4 rings that will fit each of the arms to a 65mm diameter spindle motor, so for question 1, I’m trying to find out how loose should the ring be against the router body so that it allows a smooth rotation without being too loose. For question 2, I’m trying to get the outer diameter of the CNC rings that will give a tight fit inside the arm internal diameter, so that they don’t come loose easily. Thanks
I think that this should be the goal. When the belts are under tension it’s only the back edge of the arm which will be in contact with the router so we’re not worried about backlash, we just want to make sure that everything is able rotate freely.
I don’t have an exact tolerance on them. I would expect them to be quite good as molded parts, but I don’t have anything which can measure them precisely enough to give good error bars on exactly where they are in reality.
Thanks for the quick reply. Are you able to advice the diameter in the actual design? Thanks
There is a draft angle on the part because it is molded, but it is 69.469mm at it’s narrowest part
Great, thanks for the quick response 
Maybe a silly question but does the board have to be mounted to the router, can it just sit loose or be hanging on an angle?
A little more danger that it could get bumped and damaged if it is hanging loose, but there’s certainly nothing magical about it being mounted to the router. In fact, there’s some speculation that having the board near the router may subject it to electromagnetic interference. In another topic the orignal poster built standoffs to support the board off of the vertical supports. See M4 Router Mounter Be-Gone (use any router with a side entry cord)
Hi
The options I have available is the following - The DeWalt is about $400 - so too expensive , The Bosh is about $70 , The Makita RT700C about $147 and the Makita M3700B $88 and the Metabo $71. Any suggestions would be appreciated - both the Makita RT 700c and Bosh has side entry cables - I am probably partial to the Makita as it is variable speed and aluminium body .
Thanks
take a look at
for the potential to use the cheap chinese spindles (DC 500-800w spindles for
<$100)

Not available locally - you have to run the gauntlet of our non existing post office 
So decided to pull the trigger on the middle of the road option - The Makita RT0700C and it looks like a good option 710W , aluminium body , speed control and cable side entry . Quality is good and the aluminium body should help with heat dissapation . So will now do the assembly and do my first cut this weekend . 
I have the 120v variant of that Makita router on a 3018 small desktop CNC. Its a great router. quality. You will love it. Cheers!
Hi @1Ougat. That sounds like a solid choice! How did the assembly go? I’m curious to hear about your first experience with the Makita RT0700C router. Did it perform well and fit your setup nicely? Thanks!
Might be a dumb question but is this router an option?
